To call whom, iv may concern..-

Beitknown that I, EDWIN M. ROSENBLUTH, of Philadelphia, in the State ofPennsylvania, haveinvented certain new and useful Improvements inCarriage-Lamps, whereof the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to carriage-lamps arranged to burn oil within aninclosed flamechamber provided with means to draft a supply of air fromthe exterior of said chamber to supply the burner.

It is the object of my invention to provide a lamp of the classspecified comprising a magazine arranged to contain an ample supply offree oil and an automatic capillary regulator, whereby the supply of-oildelivered from the magazine to the burner shall be uniformly maintainedas required for the maximum efficiency of the lamp regardless of thevibration to which the lamp is subjected when attached to a vehicle. I

It is a further object of myinvention to so construct and arrange such alamp that the operator may readily ascertain the quantity of oilavailable in the magazine at any given instant.

My invention consists in the novel features of construction andarrangement hereinafter more definitely specified and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of acarriage-lamp convenientlyembodyingmyinvention. Fig. 2 is a sideelevation of the oil-magazine and capillary regulator of said lamp, saidmagazine being partially sectioned to show the relation of theregulator-thereto.

Referring to Fig. 1, A is the inclosed flamechamber, whose floor A isprovided with an upwardly-projecting air-draft dome B, having anair-outlet b at its top. The bottom of said dome B opens into theair-draft chamber A within the annular flange A depending from the floorof the flame-chamber. Said flange A is provided with air-inlet aperturesa so arranged as to admit the proper supply of air to the flame-chamberA through the draft-chamber A and dome- B. The prod-. nets ofcombustion, &c., escape from said flame-chamber through the chimney A atthe top thereof. The wall A of the flame-chamber A is provided with asocket a whereby the lamp may be supported upon a suitable bracketattached to a carriage. I find it convenient to-provide theflame-chamber A with a front lens or panel of glass A and a reflector Aadjoining the rear wall A which reflector is apertured at a to permitthe transmission of light through the rear signal-jewel a However, theprecise details of construction of the flame-chamber are not of theessence of my invention, which relates more particularly to thecombination of the burner and oil-magazine with an intermediate screen,which latter is in such capillary com n1 unication with the'burner-wickand with the free oil in said magazine as to render the delivery of theoilfrorn the magazine to the burner uniform regardless of the vibrationof the lamp when attached to a vehicle.

Within the draft-dome B is mounted the burner 0, whose wick-tube 0projects through the air-outlet b at the top of said dome. Theregulator-casing D is removably secured to said burner O conveniently bythe screwthread (1, and said casing comprises a laterally-extendingcircumferential flange (1, arranged to abut against the lower edge ofthe flange A to limit the upward extension of the burner C with respectto the flame-chamber A. Within said casing D is concentrically mounted acylindrical partition D, which depends through the bottom flange d ofthe easing, to which it is soldered, and serves to support a screen ofabsorbent material D conveniently formed of a tube of wicking in whichis embedded a mass of absorbent material 61 such as cotton fibers or thelike, through which the oil is transmitted by capillary attraction tothe burner-wick C.

The oil magazine F comprises a screwthreaded neck f, fitted to thescrew-threadedflange A and the internal flange F upon the magazine isprovided with a gasket f, arranged. to impinge upon the bottom flange dof the casing D and to make an oil-tight joint therewith. As shown, saidflange F and gasket f incline downwardly toward the center of themagazine, so as to discharge within the latter any oil which mayaccidentally be deposited upon them.

The parts above described being assembled as shown in Fig. 1, theoil-magazine is in capillary communication through the screen D with thewick C", so that regardless of the vibration of the lamp when attachedto a vehicle the wick 0 cannot be overchargedwith oil, theoil deliveredto it being comminuted by its passage through said screen. Moreover,although said wick C is in capillary communication with the screen D itis capable of adjustment independently thereof through the burner C bymeans of the wickshaft 0 The operator may ascertain the quantity of freeoil available in the magazine at any instant by partially withdrawingthe regulatorcasing D from the magazine F, as shown in Fig. 2, thedepending portion of the cylinder D being obliquely terminated, asshown, to

afford the maximum view of the interior of the magazine. Such anarrangement is also advantageous in that all of the oil dripped fromsaid cylinder D is confined to the magazine F. The rod F fixed in themagazine F, indicates the depth to which the latter should be filledwith oil and being resilient is not liable to be broken.

The tube of absorbent textile material com- Y prising the screen D isconveniently fixed serves as a waterproof shelter for the matchbox Fwhose basal flange F extends from said standard, as shown in section inFig. 1,

- and serves as a pedestal for the oil-magazine F when in the positionshown in Fig. 2. Said match-box F being provided with a detent-spring fwhich normally projects through the aperture f in the standard, may

7 be released and removed from the latter at 'the will of the operatorby forcing said spring inwardly and withdrawing said box by its basalflange. There being a definite position of the burner O with respect tothe draft-dome B, in which the maximum efficiency of the burner issecured, I find it desirable to so constrnct the regulator-casing D thatthe distance between its abutment-flange dand the top of the burner Cmay be adjustably varied in the primary assembling of the parts incorrespondence with the slight variations in relative position of thedome B and the depending flange A unavoidable in the manual assemblingof the latter, and therefore I construct said casing D of two sectionstelescopically fitted, as shown in Fig. 1, which sections are firstadjusted in proper relation Within the assembled dome B and flange AandZ subsequently seamed or soldered together at Although I have foundit convenient to form the cylinder D of a cut section of perforatedmetal, as shown in Figs. 1 and 2, it is to be understood that it may beformed of other material. On the other hand, my improvements abovedescribed are advantageous in that whereas the free oil is screened fromthe burner-wick, and thus prevented from splashing through thewick-tube, only a minute quantity of the oil is suspended in theabsorbent material of the screen, the bulk of the supply of oil beingfree and visible within the magazine, so that the precise quantitythereof available may be ascertained atany instant. Moreover, the bulkof the absorbent material-being reduced to the minimum, a correspondingincrease in the oil capacity of the lampv is secured. :For instance,amagazine of the size shown when filled with saturated absorbentmaterial would contain asup ply sufficient for approximatelyliten hours,whereas with the improved'form constituting my invention an oil-supplyfor 'fifty hours service of the lamp may-be carried.

I, do not desire to limit myself to the pre cise construction hereinsetforth, as it is obvious that various modifications may be made thereinwithout departing from the essential features of my invention.
